I just noticed that the bulb for my fuel gauge went out on my 2003 Yukon XL. Does anyone know if these are easily removable? On my 95 silverado there were bases that you twisted off the cluster, pulled the bulb out and put a new one in. Is the 2003 like that? Does anyone know what voltage and wattage these bulbs are? How about a good source to find them at also? I don't think autozone will have them. I know I have a lot of questions on this one. Thanks for your help!
